Should this also work on a ATI 4650 AGP GPU? And/or is there a specific catalyst driver version that is needed? Mine isn't automatically downloading GPU work units at the moment...

Depends what CPU you have, If the CPU supports SSE2 and above then yes, but i reckon your CPU is an XP Athlon with only SSE, so No. (Similar to my XP3200+/AGP HD4650/8400GS host)

It should work on an AGP HD4650 (subject to correct CPU support), Cat 10.12 might be too old, But since you're running XP the latest driver that you can use is Cat 12.1, drivers after that have OpenCL support deprecated.

I have yet to download an Astropulse workunit. I checked for an app_info.xml where you suggested and found none. I also verified that there was no such file anywhere on my system. Any ideas? Thanks in advance.

Then - don't expect AstroPulse tasks will be available every day (they are 30x less 'in stock' than "SETI@home Enhanced" tasks)

P.S.
What you quoted is not aimed at you:
* Do NOT 'Reset' the project - all (even finished) tasks will be deleted.
* No need to search for app_info.xml - this is non-standard file (do not exist in 'standard' circumstances)

Well new WUs would be nice for starters but "don't expect AstroPulse tasks will be available every day (they are 30x less 'in stock' than "SETI@home Enhanced" tasks)" Oh, BTW ...WHY?
Anyway, I just want a few WUs to test that this release works better than the Lunat... app (read virtually nil GPU processing & virtually 100% flat-out CPU processing irrespective of standard BOINC non-geek CPU usage settings, abandoned some time past).

Now waiting for flak from Raist...The difference between 0 and 1 is greater than the difference between 1 and 1,000,000

It's actually closer to 40x. Each AP WU contains 8 MB of the raw data as recorded at Arecibo (possibly some replaced by shaped noise when needed). Each channel of a 50.2 GB tape file has enough data to produce around 400 AP WUs. But for MB, splitting produces 256 WUs from 64 MB of raw data and there's an overlap with the next group. The channel produces about 62 groups of 256 = 15872 WUs.

Update: I have now received and GPU processed my first AP v6.04 work unit. It seems that all is well. Thanks for all the great info.

I hoping to get the AMD GPU processing to work. I keep get messages to upgrade my driver to the latest version, but when I check AMD's website it says I have the latest (8.801.2.3000) the card is AMD Radeon 6450M. Any suggestions?

I only have one astropulse WU for GPU.
I understand there are no AP units being created now.
But when AP units are being created.
Will I get AP WUs just for Nvidia GPU only or will I get AP WUs for my CPUs like before along with my GPU AP WUs?

Where do you "get messages to upgrade my driver to the latest version"?

The message shows up as a notice in BIONC. I've discovered that my issue is that I'm using a toshiba which evidently has issues with drivers. The verification tool will not even load. Looks like no GPU for me.

i am new, so please excuse me, if i make this post at the wrong place.

Generally I really like the ideas behind SETI@HOME and I am willing to help!

BUT:
I had to disable the GPU usage on both my computers. My Laptop (a mobile GF 520) and my Desktop (GF GTX470) are getting under serious heat while running astropulse. Both Cards switch their fans almost instantly to max. Thats not cool - by both meanings of the word.

The GPU usage seems to be MUCH faster than CPU and i dont need my GFX card as often as the CPU - so this is really a pitty.

Is there any way to throttle the load put on the GPU? Dont get me wrong, but as long as this isnt possible i wont be using it, as i am really afraid to grill my hardware.

I'd really love to see this in the future or to receive a lil' help on how i can do this.

Firstly it is best to post questions like this in the Number Crunching Forum.

I can only see your desktop machine attached to your account, however you should not worry as Astropulse work units should not normally be sent to Nvidia cards, this was a problem at the server end and has now been rectifed.

A GFX470 should not have problems with regular work units, laptops on the other hand do heat up quite easily. I have mine on a cooling pad, works a treat.
